In the process of learning to use s4l, I don’t know how to choose to use the EM LF Electro and EM LF Magneto modules for work. I can hardly see the difference from the following introduction, and I don’t know whether the EM LF Electro module is only The electric field is generated or the EM LF Magneto module generates a magnetic field, because we know that there are electric and magnetic fields in the electromagnetic field, so if I need the existence of two physical fields in the process of using, I need to use the two modules to work at the same time ? Hope to get your help.
How to choose between EM LF ELECTRO and Magneto
details can be found in the s4l manual section 22.214.171.124 Choosing the Appropriate Low Frequency Solver
That’s great brother, your suggestion helped me a lot and allowed me to fundamentally distinguish the use of the two models.I want to ask you a question. The two low-frequency modules I mentioned above are an electric field and a magnetic field, but if I want to create a low-frequency geomagnetic field, what do I need to do? Because the electromagnetic field is composed of electric and magnetic fields at the same time.
My guess, according to the mentioned manual by using the low-frequency modules, s4l solves the E-field and H-field separately. Alternatively, a scaling method can solve a problem at high frequency and then scaling results to a lower frequency. this is some ref. https://eecs.wsu.edu/~schneidj/ufdtd/chap5.pdf . Hopefully this infor can help
